PAL in general indicates your eligibility passed, and if your BGC is also completed (or say all of the assessments are thru) then you can expect portal soon, though how soon? Imagine if IRCC support help desk can't tell you or anyone else about any specfic/approx timeline on portal - how can anyone here on forum tell how long before you get portal?
Your AST and GCkey can give you some hints like seeing DM or CoPR, when you see them, you wait say for few days and then call them, ask on your app assessments status. There many who have DM/CoPR in tracker for literally month(s) however the applicant doesn't receive portal email. This is where calling them helps to know if the portal1 was ever tiggered or not.. and in such cases when everything is cleared, the agent says portal was send/triggered but you as applicant didn't get, agent then (in some cases revalidates your email address) sends note to VO to resend portal1 and hopefully few days later, one gets portal.
How do I know this? I know because a co-worker had DM/CopR 2 months ago, never bothered to call them, then upon calling, got to know above story.
